Wire bolts are manufactured from various grades of steel, with A193-B7 representing alloy steel heat treated for enhanced strength and 2H grades for superior hardness on nuts. These are crucial for high-pressure, high-temperature (HPHT) and corrosive environments.
3. Manufacturing Process of Wire Bolts Suppliers(+ Process Flow Visual)
Raw Steel Selection: Choose certified alloy grades with full traceability; surface inspected for inclusions.
Cutting: Rods/bar cut by CNC/robotic saw to required stud length (-0/+2mm tolerance).
Hot/Cold Forging: Bolt ends head/point forged under 950–1200°C; enhances grain structure for strength.
Threading: Rolled cut threads (DIN/ANSI/METRIC) by high-precision dies, ensuring accurate pitch & fit.
Heat Treatment: Quenching + Tempering for B7 — achieves required tensile and impact strength.
Surface Coating: Black Oxide (standard), Zinc Plating, or PTFE for anti-corrosion and lubrication.
Testing/QC: Non-destructive, dimensional, and surface inspections, hardness testing, and marking. (ISO 898-1/9001-compliant)
Manufacturing Excellence:
YZ Fastener and other top wire bolts suppliers employ CNC processes, automatic galvanization lines, and microstructure analysis, ensuring each stud bolt meets demanding ISO/ANSI standards for critical industries.

10. FAQ: Professional Questions for Wire Bolts Companies
Q1: What material is A193-B7/A194-2H made from? How does it compare to other grades?
A193-B7 is Chromium-Molybdenum alloy steel heat treated for high tensile/creep strength; A194-2H refers to quenched and tempered carbon steel nuts. This makes it superior to standard carbon steel or A307 for HPHT (High-Pressure, High-Temperature) environments.
Q2: What standards do leading wire bolts suppliers comply with?
Most large suppliers comply with ASTM (e.g., ASTM A193/A194), ISO (e.g., ISO 898-1, 9001:2015), ANSI, and CE. Certifications are provided per batch, and mill test certificates (MTC) can be issued.
Q3: What is the corrosion resistance of black oxide compared to zinc plated or PTFE?
Black oxide increases salt spray resistance to 200–520 hours, zinc coating typically up to 300 hours, while PTFE can exceed 2000 hours under ISO 9227 accelerated testing—ideal for marine, chemical, or outdoor use.
Q4: Can wire bolts be supplied with custom threads (metric, UNF, BSP, etc.)?
Yes. Major wire bolts exporters are equipped with CNC threading machines and standard dies for metric (M), UN/UNF, BSW, BSPT, or as per customer supplied drawings.
Q5: What installation torques are recommended?
Installation torque depends on diameter and material. E.g., M20 B7 requires ~320 Nm; published torque tables (per ASTM/API) should be referenced for critical fittings.
Q6: What is typical usage life of wire bolts in field?
In normal operation, A193-B7/A194-2H bolts last 10+ years in mild to industrial chemical atmosphere; for marine or acid environments, special coatings or stainless upgrades recommended for 15-25 years' service.
Q7: What packing or delivery options are available from global wire bolts factories?
Bulk, kitted, box-packed, or palletized delivery; export-compliant with IPPC marking/documentation, and available express or airfreight shipping for urgent engineering projects.
